12. Check Common-Mode Rejection Ratio
a. Set:
BW LIMIT
CH 2 VOL TS/DIV
INVERT
Off (button out)
10 mV
On (button in)
b. Connect the leveled sine-wave generator output via
a 50 !2 cable, a 50 !2 termination, and a dual-input coupler
to the CH 1 OR X and the CH 2 OR Y input connectors.
c. Set the generator to produce a 50 MHz, 6-division
display.
d. Vertically center the display using the Channel 1
POSITION control. Then set the VERTICAL MODE switch
to CH 2 and vertically center the display using the Chan-
nel 2 POSITION control.
e. Set the VERTICAL MODE switches to BOTH and
ADD.
f. CHECK-Display amplitude is 0.6 division or less.
g. If the check in part f meets the requirement, skip to
part p. If it does not, continue with part h.
h. Set the VERTICAL MODE switch to CH 1.
i. Set the generator to produce a 50 kHz, 6-division
display.
j. Set the VERTICAL MODE switch to BOTH.
k. Adjust the CH 1 or CH 2 VOL TS/DIV Variable con-
trol for minimum display amplitude.
I. Set the VERTICAL MODE switch to CH 1.
m. Set the generator to produce a 50 MHz, 6-division
display.
n. Set the VERTICAL MODE switch to BOTH.
o. CHECK-Display amplitude is 0.6 division or less.
